    我国作为世界发展中大国，区域发展失衡问题已存在较长时间。为了缩短地区发展差距，我国相继制定了西部大开发、中部崛起和东北地区振兴等政策主导型的地区发展战略，引导和促进发展要素向欠发达地区逆向流动。但由于我国区域间发展基础、经济体量差距较大，通过逆要素流动实现经济、人口总量方面的协调并不适合我国当前发展现状，在共同富裕背景下，人均意义上差距缩小成为我国落实区域协调发展战略的重点。并且为了更好地发挥市场在资源空间配置中的决定性作用，自2012年开始在国家推行的“三区”（京津冀协同发展、粤港澳大湾区建设、长三角一体化发展）“两流域”（长江经济带建设、黄河流域生态保护和高质量发展）的区域发展策略中，更加侧重于引导发展要素按照市场规律充分地自主流动，实现发挥规模经济及集聚经济效应。

    本文以区域协调发展的内涵为入手点，推动区域协调发展，必须改变市场分割现状，提高市场一体化程度，构建合理的区际分工体系，形成完善、紧密的区际分工链条，实现人均意义上的趋同。基于此，本文从市场协调和产业协调两方面着手进行理论机制分析，认为发展数字经济会通过提升区际分工水平及区域市场整合水平这两个中介实现人均意义的协调发展，提升区域协调发展水平。其次，通过腾讯研究院发布的数字中国指数和30省（直辖市、自治区）2016 -2019年面板数据，构建并测算了区域协调发展水平，区际分工水平和区域市场整合水平，通过实证检验发现：一、数字经济会提升区域协调发展水平并具有区域异质性，对提升西部地区协调发展水平的作用最大，中部居中，东部最低；二、数字经济会通过提升区际分工水平、区域市场整合水平推动区域协调发展；三、数字经济会通过提升区域市场整合水平推动区域协调发展。因此本文认为，在当前数字经济发展阶段，应该加强数字经济开发力度，因地制宜发展数字经济，提升整体数字发展水平，缩小地区间数字经济发展差距与数字基础设施使用效率，促进区域协调发展。

      As a major developing country in the world, China`s regional development imbalance has existed for a long time. In order to shorten the regional development gap, China has successively formulated policy-led regional development strategies, such as the development of the western region, the rise of the central region, and the revitalization of the northeast region, to guide and promote the reverse flow of development factors to underdeveloped regions. However, due to the large gap between China's regional development foundation and economic volume, it is not suitable for China's current development situation to achieve coordination in terms of economy and total population through reverse factor flow. Under the background of common prosperity, narrowing the gap in the per capita sense has become the focus of China’s implementation of regional coordinated development strategy. And in order to better play the decisive role of the market in the allocation of resources and space, the "three districts" (the coordinated development of Beijing-Tianjin-Hebei, the construction of the Guangdong-Hong Kong-Macao Greater Bay Area, and the integrated development of the Yangtze River Delta) have been implemented in the country since 2012. In the regional development strategy of the "Yangtze River Economic Belt" (the construction of the Yangtze River Economic Belt, the ecological protection and high-quality development of the Yellow River Basin), more emphasis should be placed on guiding the development factors to fully circulate and realize independently in accordance with market rules, and to exert economies of scale and agglomeration.

       In this paper, the connotation of regional coordinated development is taken as the starting point to promote regional coordinated development. We must change the status quo of market segmentation, improve the degree of market integration, build a reasonable inter-regional division of labor system, form a perfect and tight inter-regional division of labor, and realize the convergence in the sense of per capita. of convergence. Based on this, this paper analyzed the theoretical mechanism from the two aspects of market coordination and industrial coordination and believed that the development of digital economy would achieve coordinated development in per capita terms and improve the level of regional coordinated development by improving the level of inter-regional division of labor and the level of regional market integration. Secondly, through the Digital China Index released by Tencent Research Institute and the panel data of 30 provinces (municipalities and autonomous regions) from 2016 to 2019, we constructed and calculated the level of regional coordinated development, the level of inter-regional division of labor and the level of regional market integration. Through empirical testing, we found that: 1. The digital economy will improve the level of regional coordinated development and has regional heterogeneity, and it will play the greatest role in improving the level of coordinated development in the western region, the central region is in the middle, and the eastern region is the lowest;2.The digital economy will promote coordinated regional development by improving the level of inter-regional division of labor among regions and regional market integration; 3.The digital economy will promote coordinated regional development by enhancing the level of regional market integration. Therefore, in the current stage of digital economy development, we should strengthen the development of the digital economy, develop the digital economy according to local conditions, improve the overall level of digital development, among regions and regional market integration, and promote coordinated regional development.
